Stablished in 1987 PCS are leaders in tribology test equipment. PCS has supplied over 2000 systems worldwide to over 90 countries. PCS instruments are specified in ASTM and ISO standard test methods and aid R&D experts to benchmark their formulations against market leading products and develop worldclass lubricants.
Our new ETM, designed to measure the frictional properties of lubricated and unlubricated contacts under a wide range of rolling and sliding conditions. It can apply loads up to 1600N enabling contact pressures up to 3.5GPa to be achieved using standard 3/4” AISI 52100.
ETM
The unique ball and disc set up enables mixed rolling and sliding conditions to be simulated. All three regimes (boundary, mixed and EHL) canbe duplicated, whilst applying extreme load and realistic temperatures and speeds. The frictional properties of lubricants and additives can be analysed under realistic conditions for quick comparison between formulations.

SLIM
The SLIM has been specifically designed to automatically measure the additive film formation on the upper specimen at predefined intervals throughout the duration of a test. This allows a direct systematic comparison to be made between different additive packages.
Cutting edge research using the ETM SLIM has confirmed that, at high pressure, tribofilms can be formed under full fluid film conditions and that direct metal to metal contact is not necessarily a prerequisite to forming such films. The interaction of these protective films with other lubricant components can be studied over a wide range of conditions, giving experts improved understanding of the lubricants’ performance under realistic operating conditions.
When used in tandem with the friction measurement, this provides a fundamental, real time picture of both the chemical and physical effects of the films formed in the contact.
